<u>Explanation:</u>
Given:
EP = FP
GQ = FQ
Since the sides are equal, the ΔFPQ and ΔFEG are similar.
According to the property of similarity:
On substituting the value:
Perimeter will be sum of all the sides. If y is known then substitute the value and then find the perimeter.
Answer:
We have to find the maximum number of solutions of each of the following system:
1)
Two distinct concentric circles:
Since, distinct concentric circles means that the two circles have same center but different radius.
That means they will never intersect each other at any point.
Ans hence we will get zero solutions.
2)
Two distinct parabolas:
Two parabolas can maximum intersect at 2 points this could be seen by the diagrams.
3)
A line and a circle.
A line and a circle can maximum have 2 solutions.
4)
A parabola and a circle.
It can have maximum two solutions it can be seen from the diagram.
